Hey all, I imagine this subject has been addressed here but what the heck, here goes again - if one wanted to chase the threads on one of Paul's pot metal petcocks, what die would be correct? Toaster tank fitment in mind. Many thanks!

I was looking into this a while ago and the threads were 1/8 bspp. That’s British Standard Pipe Parrallel which is good. The other pipe thread is a taper which is more difficult to find a die for. Don’t know whether the USA uses bspp but the dies are readily available in Oz and probably the UK. From memory ( no chart nearby) the tpi is 26.
